Nanofibers with side‐by‐side morphologies are electrospun from polyacrylonitrile and polyurethane using a microfluidic device. Laminar flow of the two polymer solutions through the device results in nanometer‐diameter curly nanofibers with bicomponent cross‐sections. The polyurethane half of the nanofibers can be dissolved in tetrahydrofuran, leaving a “U”‐shaped cross‐section as seen in the Figure.
